I'm sorry if this question has come up before but I've just started using PTE 5.6 and I'm new to this forum. What I would like to do is pin a particular photo to a specific point on the timeline. Let me explain, for instance, say that I wanted photo 6 to always be displayed at the 25 second point. If I then move photos about (re-order, shorten time between etc) how can I stop photo 6 accidently being moved. This is a fixed point in my creation, so it mustn't move. How can I do it? Any help or advice will be gratefully received. Cheers
